Variation in the annual growth, by sex and migration history, of silver American eels Anguilla rostrata
Silver American eels Anguilla rostrata from the East River, Chester, on the Atlantic coast of Nova Scotia, as evaluated by the temporal pattern of Sr:Ca ratios in their otoliths, showed variable patterns of migration between river and estuarine/marine waters during their yellow eel stage. Eels with a history of primarily estuarine residence were longer (total length) at migration and had higher...
متن کاملKinematics and hydrodynamics of linear acceleration in eels, Anguilla rostrata.
The kinematics and hydrodynamics of routine linear accelerations were studied in American eels, Anguilla rostrata, using high-speed video and particle image velocimetry. Eels were examined both during steady swimming at speeds from 0.6 to 1.9 body lengths (L) per second and during accelerations from -1.4 to 1.3 L s(-2). Multiple regression of the acceleration and steady swimming speed on the bo...
متن کاملFishing mortality on silver eels , Anguilla anguilla ( L . ) , in Denmark
A total of 2198 silver eels were Carlin-tagged and released at two sheltered and one exposed site in the western Baltic Sea. A total of 547 tagged silver eels were recaptured, corresponding to recoverv rates from 19 to 38% at the different sites. The majoritv of the recaptured silver cds was reporred from wirhin a radius of 20 km and within a period of less than 16 days after release. There was...
متن کاملGenomic footprints of speciation in Atlantic eels (Anguilla anguilla and A. rostrata).
The importance of speciation-with-geneflow scenarios is increasingly appreciated. However, the specific processes and the resulting genomic footprints of selection are subject to much discussion. We studied the genomics of speciation between the two panmictic, sympatrically spawning sister species; European (Anguilla anguilla) and American eel (A. rostrata). Divergence is assumed to have initia...
متن کاملHow does salinity influence habitat selection and growth in juvenile American eels Anguilla rostrata?
The influence of salinity on habitat selection and growth in juvenile American eels Anguilla rostrata captured in four rivers across eastern Canada was assessed in controlled experiments in 2011 and 2012. Glass eels were first categorized according to their salinity preferences towards fresh (FW), salt (SW) or brackish water (BW) and the growth rate of each group of elvers was subsequently moni...
